Table 5: Association status of common haplotypes of TLR4 gene with Diabetic Foot Ulcers. Fifteen haplotypes with a frequency of more than 1% was found out of which one haplotype ACATC ( value = ) was found to be associated with DFU while two haplotypes ATATC ( value = 0.012) and ATGTT ( value = 0.008) were found to be protective against DFU in a north Indian population.
